Abstract: Abstract In an arrangement of a starting and protecting apparatus structural unit (21) for a hermetically encapsulated electric motor-compressor unit (10) to the outside of which a pressure tube (15) is connected, the starting apparatus (23, 27) comprises a PTC resistor (23) and the protecting apparatus comprises a protective switch (24) responsive to excessive temperature of the electric motor-compressor unit (10) to interrupt the motor current.  In order to ensure that, on a starting attempt with the rotor of the electric motor blocked, e.g. because of an excessively high counterpressure on the output side of the compressor, operation of the compressor will start as soon as possible after blocking has been eliminated, the PTC resistor (23) is thermally connected to the pressure tube (15) and in series with the protecting apparatus (24).

Abstract: Abstract of the Disclosure In a sheet sorting apparatus of this invention, two main belts for conveying sheets run one upon another through a predetermined section, and are then separated from each other so that a triangular space is defined between them.  The shape of the space is determined by two separating pulleys and two guide pulleys.  A separator member rockable in the space has a projected portion projecting between the separating pulleys.  When the separator member is rotated, the projected portion engages one of the separating pulleys in the rotating direction to restrain the rotation of the separator member so that the sheets are guided into one of collectors corresponding to the rotating direction.

Abstract: NON-MARKING LIFTING CLAMPS            ABSTRACT      A non-marring lifting clamp for articles such as metal plates has a pair of opposed jaws mounted on opposite sides of a slot formed in the side plates of the clamp body with one of the jaws being pivotally mounted for opening and closing movements relative to the other jaw, and a lifting shackle being mounted for guided movement in the clamp body. A linkage assembly in the body couples the shackle to the pivotally mounted gripping jaw to urge the gripping jaw toward the other jaw when a lifting force is applied to the shackle. The linkage assembly includes a swing link connected to move the gripping jaw and a control link pivoted to the clamp body with a connecting mechanism coupling the control link both to the shackle and to the swing link.          A manually operated pivotally mounted handle accessible exteriorly of the clamp body operates a locking mechanism which includes a coil spring associated with the control link, this spring acting on such con-trol link and being tensioned or released by operation of the handle.  The locking mechanism includes a cam link mechanism connected to be shifted by handle movements, the cam link mechanism cooperating through the coil spring with the control link to bias the control link alternately to the jaw closing position or jaw open position. The cam link means also provides a limiting stop acting on the control link to retain it alternately in jaw open position or jaw closing position while still allowing limited opening movement of the jaws by overcoming the biasing force of the tensioned coil spring. The lifting clamp further has the other jaw carried on a manually adjustable wedge with visually observable indicia associated with this other jaw and also with the gripping jaw for the operator to visually determine the clamp's suits-bility in handling a particular size plate to be lifted.

Abstract: PROCESS FOR SEPARATING AGGRESSIVE GASES FROM GAS MIXTURES ABSTRACT OF THE DISCLOSURE A process for separating large percentages of aggressive gases such as carbon dioxide from low temperature gas mixtures wherein the gas mixture is passed through a plurality of treatment zones in series. In each treatment zone the gas mixture is first compressed to a pressure such that the partial pressure of the carbon dioxide is not greater than the critical carbon dioxide partial pressure and the compressed gas mixture is then brought into contact with a membrane more permeable to carbon dioxide than other gases of the mixture such that carbon dioxide permeates the membrane to the other side thereof. The gas mixture is maintained in contact with the membrane a sufficient time to lower the partial pressure of the carbon dioxide in the non-permeated gas mixture to less than about 40 percent of said critical carbon dioxide partial pressure. The process is especially useful for separating carbon dioxide from methane and other gases.

Abstract: ENZYMATIC TREATMENT OF BLACK TEA LEAF       Abstract A process for the enzymatic treatment of black tea leaf is disclosed. In particular, black tea leaf is wetted with water containing tannase and one or more cell-wall-digesting enzymes, such as cellulase, pectinase, papain, or hemicellulase, prior to extraction. The enzyme-moistened tea leaf is incubated in a closed system at room temperature for a few hours. The enzyme-treated tea is then neutralized with a suitable food grade base and the enzymes are inactivated by heating. The resulting treated tea can be extracted and processed in the usual manner or dried for use in tea bags in the usual manner. As a result, a higher yield of tea is obtained and the resulting instant tea has better solubility in cold water than conventional teas. The bag tea produces an infusion which does not form haze at cold temperatures.

Abstract: ABSTRACT OF THE DISCLOSURE     PROCESS FOR REFINING METAL A process for refining metal in a crucible containing a layer of molten slag, wherein molten metal passes downwardly through the slag and resolidifies as an ingot thereunder.          The slag is kept molten by passing electrical current through the slag layer and between a first electrode and a second electrode. The second electrode has liquid or gas cooling means as an integral part thereof. Current is passed between the first electrode and the second electrode through at least one electrically conductive member interposed between the slag and the second electrode. The electrically conductive member has a melting temperature above the melting temperature and below the bulk temperature of the slag. A portion of the surface of the electrically conductive member that is in contact with the slag has a temperature above the freezing temperature of the slag. The first electrode may be a consumable electrode which is partially immersed in the layer of molten slag such that it gradually melts, and drops of metal move downwardly therefrom.  The second electrode is usually the crucible but may be a non-consumable electrode which is partially immersed in the layer of molten slag.

Abstract: Abstract A valve apparatus (5) for evacuating and/or filling a refrigeration system having a hermetically closable connecting tube (4), parti-cularly a compressor capsule (1), comprises a stop valve between an evacuating and/or filling conduit (9,11) and a connecting head (3) for temporary connection to the connecting tube (4).  For placing the connecting head (8) directly on the connecting tube (4), provision is made for a sealing ring (31) which is axially aligned with an entry (28) in its housing (24) and a piston-cylinder unit (19) with a pressure chamber (20) that can be supplied with pressure medium.          The sealing ring (31), which is secured against radial deflection by a circumferential wall (32), is disposed between two annular pressure faces (33, 34) and is axially compressible thereby upon actuation of the piston-cylinder unit (19).  The sealing ring (31) and a coaxial clamping sleeve (29) which is deformed radially inwardly upon axial loading can form a series circuit which can be loaded by the force of the piston-cylinder unit (19).

The instant apparatus provides a simple and durable rotary position encoder having a plurality of sensors positioned on a first mounting member and a plurality of sensible members positioned on a second mounting member.  The apparatus is digital in design and the particular location and arrangement of the sensors and sensible members advantageously compensates for overtravel and misalignment of the encoder components.
